lillustrated in the accompanying drawings,

and particularly pointed out in the claims appended hereto, it being understood that slight changes inthe form, proportion, and minor details ofy the construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. Y 1

in the accompanying drawings which form a part; of this Vspecification it will be vseen that l:

Figure 1 is a view partly in elevation and partly in vertical section of Ynest or battery of four storage and delivery coal pooliets or bins showing a homogeneous structure 'embodying my invention.

Figure 2 is a slightly enlarged vertical section of one of the storage bins, said section being taken through one of the inlets and outlets secured to the bin, and showing the coal chute or conductor partly in section and partly in elevation. f

Figure 3 is an elevation of the top portion of one of my improved bins, showing the bin broken away vnear its topv portion, and

Figure 4; is a. vertical section taken through one -of the discharge outlets, showing in section Vthe bottom portion of the bin broken away. Y

Similar numerals of Vreference are` employed to designate lil:o or equivalent parts wherever found throughout the several In carrying out this invention it will be understood that my novel coal storage binsV or receptacles 1, 2, 3 and 4, as shown in Figure 1. may be formed of any desired material, such as iron, steel, concrete or reinforced concrete; of any suitable shape, size or dimensions, and may be nested together in any desirable manner to form a Ahonmgeneous structure, provided each coal bin or storage receptacle constitutes an absohitely airi condition, but,Y as shown, my improved structure is preferably formed of suitable concrete material 2, which may b e reinforced by metallic inserts at any desirable points throughout the structure, and each storage bin is preferably supported yat a suitable distance above its foundation by the supporting columns 3,'t0 permit a railway car,

tight structure when in its closedV truck or other suitable conveying means to be moved beneath a discharge outlet 11, for tliepurpose of receiving the coa-l discharged therefrom and conveying it to the point of utilization or any other desirable place.

Each of the storage bins is provided with a hopper-like bottom portion 5,.preferably formed integral with the walls of the structure, said hopper portion serving to direct and feed the coai to an air-tight outlet 4L suitably secured to the bottom of the bin, each outlet consising of an inner hollow casing of any suitable shape having depending walls 5 provided at its lowermost discharge end with a swinging gate 6 adapted to normally close its open end, said gate being supported'and carried by st-ub shafts 7 mounted in an outer casing 8 provided with stuffing box 9, adapted to receive one of the stub shafts, the other stubV shaft being mounted in a boss 9 formed on sait outer casing, the open lowermost end portion of the outer casing being'provided with a closure 10 hinged to said outer'casing at one side thereof, the inner peripheral portion of the closure being recessed forvthe reception of a sealing gasket 11 formed of asbestos or any other desirable material, and its cent-ral portion formed with al depending screw threaded recess adapted to receive the securing screw 12 for rigidly and tightly securing the closure to the lower end of the outer casing, said screwY 12 passing through a threaded opening in an arm 13, which is also hinged to the outer casing 8 and supported at one end thereof by a link 14,

pivotallysecured to an extension 15 formedA on said outer casing, one of the said stub shafts 7 having a lever 10 secured thereto for manipulating the swinging gate 6.

Each coal storage bin' is provided at its top portion with a central vertical extension 16, and suitablysecured and sealed to the upper surface of said extension is a coal inlet metallic frame 17, of any suitable shape, preferably annular in form, provided with a cover 18 pivoted at'one side thereof and adapted to be swung around laterally, as shown in dotted lines, Fig. said cover having a plurality of recesses formed around its peripheral portion 'adapted to receive the upper end portion of a plurality of swinging bolts 19, each bolt being pivotally secured at its lower endat 20 to the baseportion of the inlet frame, and the upper threaded end portion of each of the bolts beingv pro able cable or rope 25 for the pur-pose hereinafter described.
